TO ALL WHOM IT MAY CONCERN: v

Be it known that I, AMos GUT'TER, of Chelsea, inthe county of Suffolk, and Commonwealth of Massachusetts, have invented a new and useful Improved Blind-Catch; and I hereby declare the following to be a full, clear, and exact description thereof, which will enable others to make and use my invention, reference being had to the accompanying drawings, forming partot` this specification, -in which is shown a front view ofmy invention. j j

The object of my invention is to produce a blindLcateh easily manipulated, and conveniently reached when the blind is either open or closed.

To obtain this result, I so arrange my catch Athat it may upon the inside of the blind when the same isl shut, and outside when thrown back or opened.

At a a', in the drawings, are' represented two bent arms, hinged upon a pivot at b. The lower ends oi' these arms are attened, and so contrived as to close tightly over the shoulders, seen at It, on the spike c, being kept in thatposition by the spring d., Two spikes like that shown at c are used, one of which is attached to the window-sill, andthe other driven into the side of the house, at a convenient distance from the window. 'A hole is made in the lower bar of the blind, shown in dotted lines atf, through which hole the spikes epass. Over this hole the catch is placed, so as to cover the same, and is securely fastened in this position by a'staple placed below the pivotedjoint. The staple is shown at y. Two pins 7L z prevent the jaws m m from being forced too far apart when the blind is opened or closed. The staple g, from its position, also assists in preventing this.

The operation of my invention may be immediately seen. By pressing together the arms a a', the jaws m m will open suciently to release them from the shoulders 7c 7c, and the blind maybe thrown back or drawn to. V

Upon reaching the second spike, the momentum of the blind willpenable it to pass over` the sloping point of the same to the shoulders c c, where it will Ybe securely held Without further attention.

The arms a a projecting above the bottom bar of. the blind, will enable them to be readily grasped by the v thumb and finger. The catch, Awhich may be plated, if desired, willhave a. neat and'attractive appearance.

I do not claim the arrangement of the levers, recesses, projections, and a spring in the manner exhibited in Daniel B. Itandalls patent, October 31, 1865, No. 50,775. This arrangement is dii'erent from mine, the devices being fastened to the ylower edge of the blind, whereas mine is fastened' to the side of the lower part of a blind, so as to be on the inside when the blind is shut, and the outside when open, the spike c, in order to engage the jaws m m, either when the blind is open or shut, being compelled to 'pass through a hole in the bar, which hole is indicated in the drawings by dotted lines.. The operation is also different. Increased durability is also imparted to the device by the staple g.

What Iclaim as my invention, and desire to secure byLetters Patent, is-f l The arrangement, upon the side of the/lower bar of a blind, of arms a a', jaws m zit, spring d, pivot b, staple g, and hole f for a blind-catch, in combination with the twov horizontal spikes c, one driven into the wall of the house, and the other into the window-sill, so that said catch shalloperate to hold the blind, when either open or closed, by one set ofjaws, in the manner herein set forth.

AMOS GUTTER.
